Should I grease clockwork gears in water pressure speedo?

[Tinkerer]

I'm guessing it's not required as there doesn't appear to be any traces of grease on the gears. Then again it's an Aqua Meter speedo built about 40 years ago so it might have had grease on it once.<br /><br />Anyone know?

I wasn't building gauges 40 years ago Tinkerer, but the speedo's today have just a drop of 10,000cs silicone on the gears to prevent jerkiness throughout the scale. If you do grease it, just a small dab will do ya.

Hi Tinkerer, I tinker with antique clocks once in a while and I can say this.. don't use any grease, it is way too thick. most of the clocks I have worked on did fine with a good cleaning and a small bit of sewing machine oil applied with a hypo...on bearing points.....all grease or oil seems to do is collect dust and dirt and cause the mechanism to stick or slow down ...
